well a fraction is a/b and all whole numers (exg 1,2,3,4,5,1.5) are all over 1 so 1=1/1 2=2/1 3=3/1 6.3=6.3/1
lets say that you have 0.22 that would be 22/100 0.2=2/10 0.23=23/100 1.34=134/100 4.32=432/100 4.843=4843=4843/1000
so lets say that you have 9/4 that would be (2 fours in 9 so) 2 and 1/4 so to go back just multiply the '2' by the denomenator (bottom number or in this case it is 4) so 2*4=8 then add that to the top number so 1+8=9 9/4 very simple so 3. -15=-15/1 4. 0.31=31/100 5. 4 and 5/9= (4 times 9=36 so 36+5=41) 41/9 6. 6.2=62/10
